sl - slip network interface
pseudo-device sl [count]
The sl interface allows serial lines to be used as network interfaces us-
ing the slip protocol.
An sl interface can be created at runtime using the ifconfig slN create
command or by setting up a hostname.if(5) configuration file for
netstart(8).
The sl interface can use Van Jacobson TCP header compression and ICMP
filtering.
sl%d: af%d not supported. The interface was handed a message with ad-
dresses formatted in an unsuitable address family; the packet was
dropped.
